Figure 2 is a View at right angles to Figure l.

Figure 3 is a view in side elevation, and

Figures 4, 5 and G are views oi the locking bracket.

In Figure 1 of the drawing, a clutch housing` is indicated at l, a clutch shaft at 2 and a clutch operating sliding,l bearing,` is shown at 3. A clutch operating fork 4 is pivotally supported at 5 and is operated by a pedal in any approved manner.

A locking bracket 6 is secured to the clutch housing 1 and has secured thereto a tube 7 through Which a rod 8 passes, said rod being` connected at its lower end with a 30 bolt 9 which is guided through 'the locking` bracket 6, the latter having a bore l() for the accommodation of said bolt and this bore communicates with a recess 11 in the lower portion oi' the bracket. @ne arm o1 the clutch operating,` fork 4 is provided with an extension 12 having an enlaro'ed vtree ond 13 Which enters the recess 11 in the bracket 6 and said enlarged free end being provided With a hole 14 to receive the bolt 9. lVhen the parts are in normal operative positions, a projection 15 on the extension 12 Will be disposed in the path of the bolt 9 so to prevent the accidental dro'ijl'iinggl of sai-:l bolt. When the clutch to be locked in inoperative position, the clutch operating fork will be so moved as to bring` the hole 4 near the ree end oi the extension 12 in line with the bolt 9 so that said bolt ma),7
